Graber, for Vault Door Construction, filed August 3, 1954, Serial No. 447,544.

Prior to the present invention or discovery, usual vault door construction has included a massive crane assembly for hanging and swinging the door to and from closed position in the opening of the frame supporting the vault door, and a pressure system including a complicated array of operating bars on the front of the door, and which has the dual function of guiding the path of the door in swinging from the open to the closed position and of tightly pressing the door in the frame in the closed position.

The general objects of the present invention or discovery are to simplify the hanging means, and the pressure system of vault door construction.

The specific objects of the present invention or discovery include the provision of an improved separable door and frame engaging mechanism which has utility in itself, and which, in conjunction with an improved hinge construction, is operative on a vault door for moving the vault door horizontally between a sealing position in a frame opening and a position at which swinging of the vault door may take place.

A further specific object of the present invention or discovery is the provision of such an improved separable door and frame engaging mechanism which has a simplified construction and arrangement of its component parts, such parts being capable of economical manufacture and assembly, and the improved construction being capable of easy operation and easy and economical maintenance.

The foregoing and other objects are attained by the separable door and frame engaging mechanism, parts, combinations, and sub-combinations, which comprise the I present invention or discovery, the nature of which is set forth in the following general statement, and preferred .may be stated in general terms with reference to a vault door construction including members forming a rectangular door frame having a rectangular opening, a door movable into and out of plug fitting location in the open ing, the door frame including opposite vertical side members, and a top hinge mechanism and a bottom hinge mechanism operatively interposed between one side of the door and one of the frame side members.

The top hinge mechanism includes roller means which supports the entire load of the door and means resisting tilting of the door, and the bottom hinge mechanism inatent eludes means resisting tilting of the door. Each hinge mechanism includes a housing connected with the door and a housing connected with the supporting frame side member, and each hinge mechanism includes a hinge pin located in the frame connected housing and extending into the door connected housing, and means are interposed between each hinge pin and its associated door connected housing for moving the door towards and away from the frame.

At the other side of the door there is operatively mounted one unit of the improved separable door and frame engaging mechanism including another unit located in the other frame side member. The door and frame engaging mechanism is operative for making an engagement between the door and the frame when the door is closed and for moving that portion of the door on which the one unit is mounted towards and way from the frame.

The radial ball or roller bearing rolling against the side fiat pad surface 59 prevents tilting of the door 13.

Moreover, in the improvedv top hinge. mechanism 16, theupper housing and bearing block 38 and. the door; 13 carried thereby are arranged to move in a straight line which is horizontal in the construction 10, and means are provided for moving the block 38 and upper end of the door 13 back and forth onthe roller 63.

As shown the means for moving the block 38' back and forth on the roller 63, constitute a ball bearing nut and screw jack assembly indicated generally by 64, and which includes a ball bearing nut housing 65 which fits in; and is secured in the bore 48 of the nut mounting portion 47 of the hinge pin 45; A screw 66 is screwed in the nut housing 65 and extends rearwardly towards the door top V tongue 355 through an opening 67 formed in the wall 63 of the block 38 between the socket 58 and the socket 57. The opening 67 is formed with a bearing seat 69, and the screw 66' has a cylindrical shank 9 located inthe opening 67, and a tapered roller thrust bearing 71 is fitted on the shank 76 and seated in the seat 69. The outer end of the shank is formed with a thrust head 72., and a sprocket 73 is secured on the shank 70 between the head 72 and the inner raceway of the bearing 71. Rotation of the sprocket 73 and screw 66, by whatever means serves to advance or retract the block 38 and. supported door 13 towards and away from the hinge pin 45.

The ball bearing nut and screw jack assembly 64, as above described may be otherwise termed a push-pull rectilinear thrust mechanism connected between the hinge 45 and the door 13.

The top hinge mechanism 16 thusconstitutes in itself a novel hinge mechanism, which may be used when desired in other constructions than in the illustrated improvedvault door 10.

As shown in Fig. 18 the housing 38. has a back face 74 in which the socket SSis located, and there is also formed in the back face 74 ofthe housing 38' sloping chain channel grooves 75 and 76 for purposes hereinafter set .forth in greater detail.

The bottom hinge mechanism 17 is best shown in detail in Figs. 14, 15, 16, i7, and 2t), and includes a lower housing and bearing block indicated generally by 77, and which is secured to the lowermost tongue 35 of'thedoor front plate 26.

The hinge pin 32 is located in the socket $7, the bottom face 86 of the hinge pin is slid-ably seated on the bearing pad end surface 3%.

Immediately above the hinge pin head 84 there is seated on the shank $3, a radial ball bearing 9tl having an outer 77 into the bore 79 of; the upper block 78. Immediately maeasi above the ball bearing 90, there is fitted on the shank 83,

a needle bearing 91 the outer cylindrical surface of which is fitted in a lower portion of the bore 79. Above the needle bearing 91 a spacer sleeve 92 is fitted on the shank 83; and above the spacer sleeve 92, a needle bearing 93 is fitted on the upper end of the shank $3, and seated on the upper end of the sleeve 92. The outer cylindrical surface of the upper needle bearing 93 is fitted in an upper portion of the bore 79.

By the construction of the bottom hinge mechanism 17 as thus far described, tilting of the door 13 is prevented by the bearing pad side surface 89 thrusting against the radial ball bearing 90.

Moreover, in the improved bottom hinge mechanism 17, the lower housing and bearing block 77 and the lower corner of the door 13 to which the housing 77 is connected are arranged to move in a straight line which is horizontal in the construction 10, and means are provided for moving the block 77 and lower corner of the door 13 back and forth.

As shown, the means for moving the block 77 back and forth constitute a ball bearing nut and screw jack assembly indicated generally by 94, and which includes a ball bearing nut housing 95 which seats in and is secured in the bore 85 of the nut mounting head 84 of the hinge pin 82. A screw 96 is screwed in the nut housing 95 and extends rearwardly towards the door bottom tongue 35. The lower housing and bearing block 77 has formed therein a rearwardly opening socket 97, there being a wall 98 between the socket 97 and the socket 87, and the wall 98 has formed therein an opening 99 communicating between the socket 87 and the socket 97. The opening 99 is internally threaded, and an externally threaded thrust bear ing seat ring 100 is screwed therein, and a roller thrust bearing 101 is seated in the ring 100.

The screw 96 has a cylindrical inner end shank 102 which is fitted in the inner raceway of the roller bearing 101, and there is a thrust flange 103 formed on the shank 102 adjacent the inner ends of the threads of the screw 96, the thrust flange 103 abutting against the outer end of the inner raceway of the roller bearing 101.

The shank 102 extends into the socket 97 Where a sprocket 104 is located and secured on the shank 102. The lower housing and bearing block 77 has a rear face 105 through which the socket 97 opens, as best shown in Fig. 17. There are also formed in the rear face 105 of the block 77, upper and lower chain channel grooves 106 and 107 for purposes hereinafter set forth in greater detail.

Referring to Fig. 14, the bearing pad end surface 88 is an upper surface of the bottom end wall 108 of the housing and bearing block '77 of the bottom hinge mechanism 17. The end wall 108 has formed therein a central forwardly and rearwardly extending slot 109, and

the nut mounting head 84 of the hinge pin 82 has formed III. Separable door and frame engaging mechanism As stated above, the improved separable door and frame engaging mechanism of the improved vault door construction includes a unit 19 on the door 13 and a unit 20 in the frame side member 21. These units 19 and 20 are shown in Pig. 4 in the complete construction.

The details of the separable door and frame engaging mechanism are shown in Figs. 22 to 31, inclusive.

The unit 19 on the door 13 includes a sleeve nut 120 which is exteriorly cylindrical and has an annular flange 121 at its inner end. The door front plate 26 extends laterally beyond the outer sloping side face of the door side member 31, which to a person facing the door 13 when it is closed, is at the left-hand side of the person, and for convenience the door side member 31 is termed the left-hand side member. The portion of the door front plate 26 extending laterally beyond the left-hand side member 31, may be termed the left-hand over-hang, and in which there is formed a bearing bore 122 in which the sleeve nut is journalled.

On the rear face of the left-hand over-hang of the door front plate 26, there is located a boss 123 through which the bore 122 opens, and the flange 121 seats against the exterior end face of the boss 123. Preferably, there is interposed a bearing sleeve between the sleeve nut 120 and the bore 122, and preferably there is interposed an annular thrust disk between the flange 121 and the boss 123. The bore 122 opens at its front end through the front face of the door front plate 26, and the front end of the cylindrical sleeve nut 120 extends beyond the front face of the plate 26 and has secured thereon a sprocket 124.

The sleeve nut 120 is formed with internal threads, and an externally threaded tubular bolt 125 is screwed in the nut 120. A cupped T-head 126 is formed on the back end of the bolt 125 at the rear of the sleeve nut flange 121. The bore of the tubular bolt 125 includes a cylindrical portion 127 at its back end and a transversely square portion 128 at its front end.

The front face of the door front plate 26 has located thereon an externally cylindrical boss 129 through which the bore 122 opens concentrically. An operating and stop disk 130 is journalled on the boss 129, as best shown in Fig. 23. The disk 130 has formed therein a guide bore 131 at the right side of its axis, with reference to a person facing the door 13 when closed. The disk 130 is located between the front face of the door front plate 26 and the sprocket 124.

A trigger or control plunger assembly indicated generally by 132 and shown detached in Fig. 26, is operatively associated with the tubular bolt 125, the operating and stop disk 130, and the door front plate 26. The trigger or control plunger assembly 132 includes a shaft indicated generally by 133, and including a front square portion 134, having a back shoulder and an intermediate enlarged cylindrical washer slidable on a back externally threaded cylindrical portion 136. In the assembled door 13 the shaft 133 is located in the bore of the tubular bolt 125, the shaft square portion 134 slidably fitting in the bore square portion 128, and the shaft washer 135 slidably fitting in the bore cylindrical portion 127.

The trigger or plunger assembly 132 furthermore includes a T-head 137 having an internally threaded tubular shank 138 which is screwed on the end of the threaded shaft portion 136.

The T-head 126 of the tubular bolt 125 has formed therein a rearwardly opening rectangular cup 139, and the T-head 137 of the assembly 132 slidably fits in the cup 139 of the T-head 126 in the assembled door 13.

A spring helix 140 engirdles the threaded portion 136 of the shaft 133 between the washer 135 and the outer end face of the shank 138, and the spring helix 140 reacts between the washer 135 and the T-head shank 138.

On the outer end of the square shaft portion 134, be yond the sprocket 124 in the assembled door 13, there is secured an actuating lever 141 from the rear face of which there extends a plunger 142 which fits in the guide bore 131 of the operating and stop disk 130.

Above and to the right of the axis of the shaft 133, with reference to a person facing the door 13 when closed, in the front face of the door front plate 26, there is formed a' forwardly opening socket 143, in which the a ian-eel roar endof theplunger 142 may be slidably received, as best shown in Fig. 27. i i i I r '7 In Fig. 27, the parts of the door and frame engaging mechanism are shown in their relative positions when the door has been open and' has then been swung to the position for plug-sealing operation, or when the door has been moved outwardly from its plug-sealing position and is-ready to be, swung open. When the parts of the unit 197are in the positions shown in Fig. 27, the plunger 142 is engaged in the socket 130 preventing any rotary movement of the parts in, the unit 19.

The composite frame side member 21 at the left-hand side. of the frame with reference to a person facing the door. when the door is closed, includes a seal member 21-1 which slopes from front to rear laterally from the larger front end opening of the frame to the smaller rear end opening thereof. The front end of the frame side seal member 21-1makes junction with a vertical front frame finish-plate 144 which is overlapped by the lefthand over-hang of the door front plate 26 when the door is-in the position shown in Fig. 27.

The unit 2110f the door and frame engaging mechanism is mounted in the frame finish plate 144 at a level for interaction withthe unit 19.

Referring particularly to Figs. 4, 22, 24, 25, and 27 to 31 inclusive, the unit 20 of the door and frame engaging mechanism constitutes a compartmented housing including an externally cylindrical body 145 at the front endof which there is located an outwardly extending annular flange 146 and at the back end of which there islocateda circular back wall 147. The front end of the cylindrical body 145 and the annular flange 146 seat in and are secured in a counter-bored opening 148 formedin the front frame finish plate 144 whose front face 149 isvertical and perpendicular to the horizontal axis of the cylindrical exterior surface 150 of the body 145-.

The compartments of the body 145 include a forwardly opening front compartment 151, an intermediate compartment 152, and a back compartment 153. A front partition wall 154 has parallel front and back faces 155, and 156 parallel with the vertical front face 149 of the front frame-finish plate 144, the front partition wall 154 being part of the body 145 of the unit 20 and separating the front compartment 151 and the intermediate compartment 152, each of which is interiorly cylindrical and concentric with thecylindrical exterior surface 150. The wall 154 has formed therein a slot 157 which is symmetrical with respect to the horizontal axis of the cylindrical. surface 150.

The slot 157 is vertically elongated, and has parallel vertical side faces 158 and 159 merging at opposite ends with semiacylindrical top and bottom faces 160 and 161, as .hest shown in Fig. 30.

The back compartment 153 of the unit 20 is a socket opening forwardly into the intermediate compartment 152and havingparalleltop and bottom horizontal faces 16 2.and 163 equally spaced on opposite sides of a horizontal plane 164 passing through the horizontal, axis 15650.01? the cylindrical exterior surface 150 of the body 145, as best shown in Fig. 31.

At opposite sides of the, plane 164, the intermediate compartment. 152 has sectoral top and bottom faces 165 and 166 making junction with thesocket faces 162 and 163, respectively, at bevelled or rounded corners 167 and-168.

The cupped T.-head 1260f the bolt 125 isgenerally in.the shape of;elo ngated rectangular parallelopiped symmetrical with respect to the axis 150 0, and having roundedporners TheT-head 126 has parallel side faces 1 59., d170 whicharespaced fromeach other a distance less than the spacing of'the side faces 158 and 159 of the slot 157; and, the T -head 126 hasparallel end faces 171 and 172w job are spaced from each other a distance lessthan the distances fromeach other of the nearest portions of the topandv bottom faces160 and 16 1 of thelslot 157. In other words, when the 'T-head 126 Iis.

positioned as in Figs. 27, 28, 30, and3l, there isfsub stantial. clearance between the T-head' 126 and slotv 157.

As, above stated, the T-head 137 slidably fits in the cup 159 of the, T-head 126, and the T-head 137 has side faces 173 and 174 which are spaced from each other a distance slightly less than is the distance betweenthe socket faces 162 and 163.

The unit 19 of the door and frame engaging mechanism may be more definitivelyv termed an anchor and push unit, and the unit 20 ofv the. door and frame engaging rn echanism may be more definitively termed a detent and thrust reacting unit. In a similar and more definitive manner, the cupped T-head- 126 may be termed an anchor and push T-head; the partition wall 154 may be termed a slotted detentwall; the sectoral top and bottom. faces 165 and 166 may. be. termed thrust reacting faces; the socket compartment 153 may be termed an anti-twist socket; and the T-head 137 may be termed an anti-twist T-head.

The anchor and push unit 19 may also be termed a separable push-pull rectilinear thrust mechanism or unit.

In the complete vault door construction 19, the separable door and frame engaging mechanism is operated in co-.ordination with the hinge mechanisms 16 and 17', and other parts, as is hereinafter described in detail.

However, the door and frame engaging mechanism, as thus far described is capable of independent use, and manual operation, as follows Referring to Figs. 27 and 30, the door 13 has been moved to a position in which the T-head 126 with its side faces 169and 170. in the vertical position and in registering relationship with the vertical side faces 158 and 159 of the slot 157, has been pushed through [the slot 157-until the back face 175 of the T-heacl 137 just touches the sectoral faces 165 and 166. The trigger or control plunger assembly 132 has its plunger'142 seated in the socket 143 of the door front plate 126, thus preventing any turning of the assembly 132 and the bolt 125, and preventing any further backward movement of the shaft 133 and the spring press-ed T-head 137 thereon.

When, however, the door 13 is pushed a slight distance further towards the frame 11, to the position shown in Fig. 28, the assembly 132 remains horizontally stationary, and the door front plate 26 movies horizontally to a position in which the socket 143 is disengaged from the plunger 142. The assembly 132-and parts rotatable therewith are then free to rotate, the actuating lever 14-1 being in the upper position shown in Fig. 36.

If a twisting or turning force or torque is then applied to the operating and stop disk 13%, the lever 141 and parts movable therewith will turn through an of to the position of the disk 131 shown in Fig. 23. The disk 13% has formed in its outer periphery a curved outwardly opening stop recess 176, and a spring loaded bail 1'77 is mounted on the door front plate 526 and projects from the front face thereof at .a position so as to be received by the stop recess 176 of the disk 1323 at the relative positions of the parts shown in Fig. 23, and which positions other parts-as shown in 29 and 39.

The sprocket 124 is then rotated so as to turn the nut and screw the bolt in the nut 129, the anchor and push T-head 1'26 pulling against the back face 156 of the slotted detent wall 154, and the anti-twist T-h'ead 137 advancing into the anti-twist socket 153, until the parts have attained the relative positions shown in Fig. 22, in which the door 13 .is plug-sealed in the opening of the door frame 11.

Reversing the above described cycle of operations of the door and frame engaging mechanism serves to return the parts from the engaged positions shown in Figs. 22 and 32 to the disengaged positions shown in Figs. 27 and 36 Fig. 43 is a fragmentary isometric view showing certain parts of the improved door construction, including parts of the separable door and framing mechanism, and parts of the hinge mechanisms, the illustrated parts being in their relative positions when the door is ready to be opened or is ready for seal-plugging in the door frame. Fig. 36 is a corresponding elevational view.

Fig. 44 is a view similar to Fig. 43, showing the relative positions of the illustrated parts, after the door has been seal-plugged in the door frame. Fig. 32 is a corresponding elevational view.

Fig. 45 is a fragmentary view similar to Figs. 43 and 44 showing the relative positions of the illustrate-d parts at an intermediate point between the positions shown in Fig. 43 and the positions shown in Fig. 44. Fig. 39 is a corresponding elevational view.
